nvme: assert valid nvme_qpair_construct parameters

Browse Source 
Document the assumptions made by qpair_construct using asserts.

These values can't actually be 0 in practice due to the way they are
derived, but scan-build can't see that.  It is also useful to have these
asserts in case of future modifications.
